Vancouver Sun - - CITY -

Drug resistance is one of the top five hu­man health threats. That’s when viruses, bac­te­ria and fungi can no longer be killed by the drugs that we have to deal with them. Ac­cord­ing to the World Health Or­ga­ni­za­tion, drug resistance will kill more peo­ple than can­cer, di­a­betes and cholera com­bined.

When it comes to surgery, self in­fec­tion of the sur­gi­cal site is a prob­lem. Your nose is home to many harm­ful germs, even su­per­bugs, and is a lead­ing source of post-sur­gi­cal in­fec­tions.

In the U.S., up to 60 per cent of hos­pi­tals re­move these nasal germs with topical an­tibi­otic ap­plied to the nose be­fore surgery to re­duce the like­li­hood of sur­gi­cal site in­fec­tions.

De­spite chal­lenges that in­clude low pa­tient com­pli­ance, a five-day treat­ment regime and in­creas­ing an­tibi­otic resistance, nu­mer­ous ran­dom­ized con­trol tri­als in­di­cate a 40 to 60 per cent drop in these hos­pi­tal-ac­quired in­fec­tions.

For this rea­son, the World Health Or­ga­ni­za­tion rec­om­mends this pre-sur­gi­cal treat­ment for ortho, spine and car­diac surg­eries.

In Canada, only Van­cou­ver Coastal Health re­quires univer­sal presur­gi­cal nasal dis­in­fec­tion for all ma­jor surg­eries. It uses On­dine

Biomed­i­cal’s pho­to­dis­in­fec­tion tech­nol­ogy, a pain­less six-minute pro­ce­dure.

The in­fec­tion re­duc­tion has been sig­nif­i­cant since the tech­nol­ogy was in­tro­duced nine years ago.

It has con­trib­uted to an 80 per cent re­duc­tion in se­ri­ous in­fec­tions.

On­dine and Van­cou­ver Coastal Health are now ex­plor­ing if this nasal treat­ment can be used to help pre­vent COVID-19.

We in­vited Carolyn Cross of On­dine Biomed­i­cal to join us for a Con­ver­sa­tion That Mat­ters about the laser treat­ment. See the video at van­cou­ver­­ver­sa­tions-that-mat­ter.

Con­ver­sa­tions That Mat­ter is a part­ner pro­gram for the Mor­ris J. Wosk Cen­tre for Di­a­logue at Si­mon Fraser Univer­sity. The pro­duc­tion of this pro­gram is made pos­si­ble thanks to the sup­port of view­ers like you. Please be­come a Pa­treon sub­scriber and sup­port the pro­duc­tion of this pro­gram, with a $1 pledge at ypxyds
